How has the FLUID trial, which showed no significant difference in death or readmission rates between Lactated Ringer’s solution and normal saline, influenced your approach to IV fluid management?
The choice between normal saline and Lactated Ringer's should be individualized. Normal saline is preferred in patients with hyponatremia or metabolic alkalosis. Lactated Ringer's is preferred in patients with hyperchloremic acidosis, and it should be avoided in patients with hyponatremia since its ...
What approaches can we take to initiate therapy and improve survival rates in patients with HLH?
At our institution, we have comprised a multidisciplinary team to help treat these patients. The team or "HLH task force" as we like to call ourselves is comprised of a clinical immunologist, rheumatologist, dermatologist, critical care physician, hepatologist, BMT attending/hematologist, infectious...
Do you accept a decline in eGFR during aggressive diuresis for heart failure if the patient is successfully decongesting, given data suggesting modest eGFR decline with improved congestion may still be associated with lower mortality?
Yes, I accept a modest decline in eGFR during diuresis in patients with heart failure. Previous studies of patients hospitalized with acute decompensated heart failure have shown that mortality and readmission rates are reduced by effective decongestion even if the creatinine rises. The study by Oka...
How do you approach initial anticoagulant selection in hemodynamically stable hospitalized patients with newly diagnosed pulmonary embolism?
Low-molecular-weight heparin demonstrates the greatest benefit in patients with cancer-associated pulmonary embolism, intermediate-risk PE, and those requiring outpatient management. While LMWH shows superior efficacy and safety compared to unfractionated heparin across most patient populations, cer...
Do you perform routine screening for latent tuberculosis in a patient who resides in the United States, has frequent, 1-2 week trips to see family in a highly endemic country, but who otherwise has no significant risk factors or high risk exposure activities?
Absolutely. I perform annual screening on persons with the described exposures. The screen is fast, safe, and easy for the patient. A goal is to eliminate all new cases of tuberculosis in this country. To accomplish this, we must identify all potential cases and treat them accordingly.
When do you start steroids for radiation pneumonitis?
Great question on a relevant clinical topic. It's very important to remember that pneumonitis is a diagnosis of exclusion. Sometimes, if the timing is right and the patient's presentation is typical, there is a tendency to move quickly to the conclusion that the symptoms are caused by pneumonitis. R...
What is your approach to a patient with undetectable MMR titers checked prior to or during immunosuppression and a history of MMR vaccination in childhood?
MMR titers are good correlates of protection. If any titer is undetectable it could be one of these situations: Primary failure. The components of the MMR have different efficacy. Two doses of appropriately given MMR will have 96+% against measles, but only 88% for mumps. Thus 1 in 10 appropriately...
How do you approach management of new onset ILD in a patient with RA who is otherwise well controlled on methotrexate or leflunomide?
We do not have any randomized controlled trials for DMARDs in RA-ILD. Most of the data is case series or retrospective analysis. Nonetheless, we can use current data to at least make clinical decisions until we receive more direction from high-quality clinical trials. We now know that in general met...
Would you stop Dupixent in an asthma patient who has good asthma control and notes improvement in loss of smell, but shows notable eosinophil elevation after 4-5 doses of the medication?
Transient eosinophilia has been reported in patients treated with Dupixent, likely related to downregulation of eotaxin and adhesion molecules resulting in impaired eosinophil migration into the tissues (Castro et al., PMID 29782217, Olaguibel et al., PMID 35522053). This phenomenon is typically see...
What is your approach to patients with chronic hypoxemic respiratory failure who have apparent higher oxygen needs during hospitalization but no clear acute/decompensated respiratory illness?
Will work them up completely for infection, PE, COPD exacerbation, heart failure/cardiac etiology. If no convincing reason for decompensation and they are stable, I will have them do a 6 min RT walk test to determine oxygen needs and have them follow up with PCP or pulmonary for further PFTs or othe...
